Tommy Wood

Dr. Tommy Wood returns — now on JRE after appearing on Ferriss #851. Brain health, dementia prevention, and why 45-70% of dementia is preventable. APOE4 genetics, the importance of cognitive challenge, and making mistakes as brain training. Cross-podcast reference.

Curious

Wood repeats his thesis from Ferriss #851: dementia is largely preventable through lifestyle. APOE4 amplifies risk 2-6x but environment matters more than genetics.
Wood cites music and language learning as the most effective cognitive challenges for brain health. Third cross-podcast reference.

Highlights

Your brain needs to fail to grow
Making mistakes at new tasks — language learning, instruments, complex games — builds neural resilience. Easy tasks don't.
